Your summer assignment is to create a free account for yourself on code.org and then to complete at least 85% of the "CS Fundamentals: Express Course" on this site. You can use either your school or your personal gmail account to create your code.org account.
Note that you must be logged into code.org while completing the problems in order to receive credit. At the beginning of the school year your instructor will check to see how much of this course you have completed. The result will form a large portion of your Q1 homework grade.
The estimated time required to finish this assignment is 20 hours. It is best to do a few hours each week instead of marathon sessions near the end of the summer.
If you get stuck on a problem, simply move on as you are not required to complete every single item. However, if you want help in deciphering a problem, you can email Mr. Sarkar at csarkar@stamfordCT.gov over the summer at any time.
